The OB1-300 Combo houses a new 15” Eminence neodymium speaker in a carefully designed front-ported cabinet, and this configuration is the ideal match for the OB1’s fearsome tonal platform. The two elements combine to offer an immediate attack and a seriously punchy low end, dishing out warm contemporary cleans, grinding vintage grit right up to heavily distorted mayhem . Most importantly, the OB1-300 Combo remains focused at all extremes of its wide-ranging tone controls.
